Right now I am on my second ATO. I recently ordered my first Tunze last week online; setup was very straightforward and easy, and all seemed well. As soon as I plugged in the unit, the pump kicked on and topped off my 30g beautifully...and that was it. The sensor never triggered, even after I siphoned out enough water to drop it below the sensor completely. The only way I could get the ATO to work was to unplug it and replug it. My assumption was a faulty sensor and so I went ahead and exchanged it for a new one.
Fast forward to today and I have the exact same issue, leading me to believe that I have either incorrectly installed the system or I have extremely bad luck with them! I currently have my water level sitting completely below the sensor with no trigger to the pump at all. Any help here would be greatly appreciated because I've heard great things about the Tunze ATO.
